(24) Ag7'ion heterogamias, sp. nov. 



Male with the abdomen red, that of the % greenish-black. Labium, apex of labrum, 

 a space along the inner margin of each eye, connected by a transverse line, pale. 

 Vertex of head black with pale post-ocular spots, which are nearly connected by a pale 

 line. Prothorax more or less spotted. Dorsum of the mesothorax with the median 

 crest and two lateral lines pale, rarely reddish ; sides of thorax more or less pale. Legs 

 pale or reddish, with long black spines. Wings with elongate pterostigma of an obscure 

 colour. Post-costal area of both pair with a double row of cellules for a great part of 

 its length. Abdomen in the ^ generally with the apical half of the 6th, the 7th, and 

 more or less of the 8th black, the rest nearly entirely red, and not very variable ; in the 

 % the abdomen is nearly entirely greenish-black above, with the basal margins of the 

 3rd to the 7th segments very narrowly pale and the apices of the following obscurely 

 and narrowly reddish, or testaceous. 



Z superior appendages as long as the loth segment somewhat incurved, the apex 

 black and armed at its extremity with a minute tubercle directed inwards ; inwardly, a 

 short way behind the apex, is a second minute spine or tubercle, from which the 

 appendage is greatly produced downwards and dilated : at the apex of the lower margin 

 of the dilated portion inwardly there is a small black spine directed inwardly, and the 

 margin itself now becomes thickened and strongly raised, and near the base of the 

 appendage gives rise to another black spine directed upwards. Lower appendages 

 elongate-triangular, extending beyond the dilated portion of the superior pair, hardly 

 curved inwards, red, terminating in a minute tubercle or spine. Tenth segment angu- 

 lately excised. 



Female superior appendages acute, triangular, black or obscurely reddish ; valvules 

 pale, their appendages darker. (Plate V. fig. 3.) 



Length of abdomen 36 — 40 mm. ; of hind-wing 29 mm. ; expanse 64 mm. 



Hab. Kauai, widely distributed from near sea-level to 4000 ft. Allied to A. 

 oceanicum and A. blackburni, the females of which are quite distinct from the present 

 species by their general appearance, and the males by the form of the appendages. 



PSOCIDAE. 

 In this group we have followed Renter in the description of wing-nervuration. 



Psocus Latr. 

 (i) Psocics haleakalae, sp. nov. 



Head with the labrum dark, the post-clypeus pale with longitudinal dark lines, the 

 front more or less pale, with dark markings. Eyes in the t not very large, the space 

 between them in a front view of the head being (where least) fully equal to, or rather
